Cindy, glad to hear you're holding your own.
For the computer - small independent shops can sometimes fix problems cheap. If you're running WinXP, try a system restore (pick a date before you had problems). If not, do you have a system restore cd? You'll lose all data, but it sometimes works.
I'm in charge of the care/feeding of a small network (5 pc's and an NT server) and 3 pc's at home, and have no formal training, so I know what it's like to try to "just make the darn thing work".
Email me if you want more free advice - worth every penny .
